Abstract
Background
Although recent research evidence suggests an association between household air pollution
from solid fuel use, such as coal or biomass, and cardiovascular events such as hypertension,
little epidemiologic data are available concerning such exposure effects on cardiovascular
endpoints other than hypertension. We explored the association between in-home solid fuel
use and self-reported diagnoses of cardiovascular endpoints, such as hypertension, coronary
heart disease (CHD), stroke, and diabetes.
Methods
We analyzed 14,068 Chinese adults, aged 18 years and older. Odds ratios (OR) and the
corresponding 95% confidence intervals (CI) were estimated using logistic regression models
for the risk of each outcome after adjusting for potential confounders.
Results
The use of solid fuel in home was significantly associated with an increased risk for
hypertension (OR 1.70, 95% CI 1.40 to 2.07), CHD (OR 2.58, 95% CI 1.53 to 4.32), and
diabetes (OR 2.48, 95% CI 1.59 to 3.86), after adjusting for potential confounders. Compared
with individuals in the lowest tertile of the duration of solid fuel exposure, those in the
highest tertile of the duration of solid fuel exposure had an increased odds of hypertension
(OR 1.73, 95% CI 1.45 to 2.06), stroke (OR 1.87, 95% CI 1.03 to 3.38), and diabetes (OR
3.18, 95% CI 2.11 to 4.78).
Conclusions
Our data suggest that in-home solid fuel exposure maybe associated with increased risk for
hypertension, CHD, stroke, and diabetes in the Chinese adult population. Further large-scale
longitudinal studies are warranted to confirm these findings.

• The Surgeon General has determined that there is no safe level of exposure to ambient smoke!

• If you smell even a subtle odor of smoke, you are being exposed to poisonous and carcinogenic chemical compounds!

• Even a brief exposure to smoke raises blood pressure, (no matter what your state of health) and can cause blood clotting, stroke, or heart attack in vulnerable people. Even children experience elevated blood pressure when exposed to smoke!

• Since smoke drastically weakens the lungs' immune system, avoiding smoke is one of the best ways to prevent colds, flu, bronchitis, or risk of an even more serious respiratory illness, such as pneumonia or tuberculosis!
Does your child have the flu? Chances are they have been exposed to ambient smoke!
